JOHN CHIVILL, OF CHICAGO, ILLINOIS ASSIGNOR TO THE WEBSTER & COM- STOGK MANUFACTURING COMPANY, OF SAME PLACE.

SHAFT-HANGER.

SPECIFICATION forming part of Letters Patent No. 327,524, dated October 6, 1885.

Application filed July 6, 1885. Serial No. 170,692. (No model.)

To all whom it may concern.-

Be it known that I, JOHN CHIVILL, of Ohicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in ShaftHangers, of which the following is a description, reference being had to the accompanying drawings, in which- Figure 1 is a side elevation of said shaft. Fig. 2 is a central longitudinal sectional view thereof, and Fig. 8 is a horizontal sectional view in plan upon the line or m, Fig. 1.

Like letters of reference indicate like parts in the different figures.

The object of my invention is to provide an adjustable hanger for shafting which may be more especially adapted for use in conveyers, and which shall possess the advantages of a solid hanger, while at the same time the wear thereof may be taken up without the use of the usual divided box, the parts of which are connected by means of bolts and nuts at the sides of the shaft, which are liable to become 'detached and thereby cause injury or breakage.

In the drawings, A represents a conveyortrough,which is preferably provided with vertical slots, a, at its top, one of which is shown in Fig. 1, to which are attached, by means OI bolts 1) I) my improved hanger B, the same being made vertically adjustable by means of said bolts in the slots a. Said hanger consists of ayoke cast in a single piece, substantially in the form shown, and provided with a suitable bearing for the reception of the shaft 0. Over said shaft I place a cap, D, said cap being provided with flanges (Z (Z d d, better shown in Fig. 3, adapted to fit in grooves or offsets in the hanger B, so as to retain said cap firmly in place when in position. The cap D is provided with an upwardly-projecting stem, (2, having laterally-extended portions or arms (1 d said cap, stem, and arms being preferably cast in one piece, substantially as shown. The arms d d are firmly attached by means of bolts or screws d d to the yoke or 5 hanger B, a suitable packing, 61* (1, consisting of strips of leather, paper, or other suitable material being inserted to enable the cap D to be adjusted to fit the shaft 0. As soon as said shaft or the bearing in which the same is in sorted becomes worn a layer of the packing d may be removed and the screws (1 tightened, by which means said wear may be readily taken up at any time. An oil-hole, 02 Fig. 2, extending downwardly through the stem (2,

is likewise provided forlubricating said hearing, said oil-hole being preferably provided with a suitable packing and a stopper, d.

It will be observed that all the adjusting screws are either upon the outside or top of the conveyor, there being nothing therein to become loose or detached, and thus cause injury thereto.

It is obvious that the shaft may be readily removed from its bearing without displacing the hanger, while the arms d d serve as a brace to stiffen the latter.

Having thus described myinventiou,whatI claim, and desire to secure by Letters Patent, 1s

1. In a shaft-hanger, the combination of the yoke B, cast in one piece, and a cap provided with-a hollow stem, (1, and arms d d substantially as and for the purposes set forth.

2. The combination of the yoke B, cast in one piece, and adjustable cap D, said cap having a hollow stem, (1, arms d (1 adjustably secured to said yoke, and flanges d, substantially as and for the purposes set forth.
